Google has launched Knol, its take on Wikipedia:

With Knol, we are introducing a new method for authors to work together that we call “moderated collaboration.” With this feature, any reader can make suggested edits to a knol which the author may then choose to accept, reject, or modify before these contributions become visible to the public. This allows authors to accept suggestions from everyone in the world while remaining in control of their content.

Mostly medical articles right now, though there are a few gems.

Extremely awesome indeed.

Update: Robb Irrgang, he of pretty skin and good taste, pointed out the difference in the released version of the site versus the original mock-up Google posted a few months ago.

Perhaps I have a predilection towards serif faces for body copy; The original was definitely more aesthetically pleasing and felt much more literary. The design felt more balanced overall, and more distinct.

I wonder why they changed it.
